Which do you prefer? An electronic Ereader or a book?

Me I would pick a book over an Ereader any day, I love the feel and smell of a new book theres no creases down the spine, so you start reading it half open to keep it that way. Yes I  do prefer a book butttt I own a kobo (Ereader) I like to know I have another book with me incase I finish the one im reading and im sure my handbag is not big enough for 2 books.
